# Drag (click and hold) your mouse across the # image to change the value of the rectangle value = 0 def draw(): fill(value) rect(25, 25, 50, 50) def mouseDragged(): global value value = value + 5 if value > 255: value = 0
THIS EXAMPLE IS BROKEN
The mouseDragged() function is called once every time the mouse moves while a mouse button is pressed. (If a button is not being pressed, mouseMoved() is called instead.)
Mouse and keyboard events only work when a program has draw(). Without draw(), the code is only run once and then stops listening for events.
